47. Corporate Office Properties Trust

COPT is a specialist in office space for the military and its contractors — an area at risk for government spending cuts. To brace for possible changes, the company has been aggressively selling non-core assets, parting with more than 50 buildings including all of its holdings in Montgomery County. It also agreed, with partner Facchina Group, to drop plans to build a technology park in Charles County in August.

Trivia

COPT owns properties in three states outside the Mid-Atlantic: Texas, Colorado and Alabama.
